I am using TVD spatial schemes (limited linear) and unstructured grid with temporal scheme with timeadjustable on. The result I get when apply backward is that the pressure diverges for a few iterations whenever update is called. Case solved: sliding mesh boundary condition caused the pressure oscillation.
